A fuel injection pump, which is equipped with a cam drive device that produces a discharge movement of at least one pump piston, and in which a portion of the cam drive device supported within the pump casing determines when the injection starts. cam drive relative to the rotating part for adjustment, against the forces of two parallel return springs, by means of an adjusting piston which is loaded by the delivery pump pressure as a function of the rotational speed. In the rotating type, the adjusting piston 30 is configured so that the other spring 46 engages only after the adjusting piston 30 has been pushed back a predetermined distance against the force of the other spring 33. , the predetermined distance h is preadjustable by inserting washers, and both springs 33,
A fuel injection pump characterized in that the rods 46 are arranged coaxially and that the rods 46 are fixed in the casing in the axis of these springs. 2. Fuel injection pump according to claim 1, in which a sleeve 50 cooperating with one of the springs 46 and the adjusting piston 30 is slidably guided along the rod 47. 3. The fuel injection pump according to claim 1, wherein the rod 47 is fixed in the hole 48 by press fit.
